How long will it last?
Our estimateSupported until May 2021 · Buy-by May 2019
Apple doesn't publish an end date, but iPhones have a consistent ~3-year update track record — on that basis the Galaxy J4 (2018) should be supported until around May 2021. Buying it today still gets you about -5.2 years of safe use, and Apple's written legal minimum is 5 years (verified June 2026).

Frequently asked questions
How long will the Galaxy J4 (2018) get updates?
It is end-of-life. The J4 received a single update to Android 9 and stopped getting patches around 2021.
Is the Galaxy J4 fast enough?
Only for basic use. Its quad-core Exynos 7570 and as little as 2GB RAM make it slow with anything demanding.
Can I still use a Galaxy J4 today?
It handles calls, messaging and light browsing, but the absence of security updates makes it unsafe for sensitive accounts.
How does the Galaxy J4 charge, and is it cheap to buy now?
It charges slowly over the older microUSB port at just 5W, so its 3000mAh battery takes a while to fill. On the used market it now sells for around $40, down from a $160 launch price.
